Today we offer computers working a certain value which however tell us the slightest shock "Goodbye". This protection more than filled his role well. The shell completely surrounds the One and allows during its fall (unfortunately tested by me) dabsorber the shock first. By cons after a few falls is the protection that toast (and better). satisfied with the product do not hesitate to take you two for the price rather than because mine is now cracked. Fast delivery. Lightweight package.
